A practical approach to diode based in vivo dosimetry for intensity modulated radiotherapy

A method for in vivo entrance dosimetry, using point detectors, in intensity modulated radiotherapy has been clinically evaluated. Diode dosimetry was performed for treatments of the head and neck and prostate regions. The results were good; 92.2% of the measurements showed deviations within +/- 5% of the expected values.
